Top performance cassette deck
The Sony TC-K35 stereo cassette deck combines convenience and high performance at a surprisingly affordable price. As heir to Sony's many-years of excellence in tape recording, the K35 offers superior magnetic, mechanical and electronic technology. The end result is reliability and accurate reproduction of musical sound.
Ferrite0and-Ferrite head
The K35 incorporates Sony's exclusive ferrite-and Ferrite record/play head. Because ferrite is extremely hard, it provides exceptionally long service life - up to 200 times longer than permalloy. In addition, ferrite's hardness allows mirror-smooth polishing for low wear better tape-to-head contact, and better sound. And ferrite's superior magnetic permeability at high frequencies contributes to the extended high frequency response of the TC-K35
Low-Distortion Electronics
Sony's attention to detail extends to the electronic design, as well. The critical head/playback amplifier for example, uses a unique, patented, direct-coupled, design to insure low distortion. As you would expect, the K35 also incorporates the Dolby noise reduction system, providing Signal-to-Noise Ratio improvement of up to 10 dB at 5 kHz and above. And a built-in 19 kHz filter prevents Dolby circuit mistracking when you record FM stereo broadcasts.
DC Servo Tape Drive
The motor of the TC-K35 is a Sony Tri-Duty DC Servo Motor with an internal frequency generator. As the motor turns, the generator produces a frequency proportional to the motor's speed. In this way, the generator reports any speed variation to the servo-control electronics which provide instantaneous correction. This, along with a dynamically balanced oversized flywheel, assures smooth, stable tape travel, with wow and flutter of only 0,05% (WRMS). And the unique aluminum, steel and rubber motor housing helps maintain this accuracy under a wide variety of temperature and load conditions.
Rugged, Flexible Transport
The K35's Sony-built transport provides particular benefits. First, the special "Auto-Play" feature allows you to rewind to the beginning of the tape and automatically transfer to the playback mode. Second, you can "punch in" directly from the play mode into the record mode, simply by pressing the record button. This allows additions to pre-recorded material. Next, REC Mute deletes unwanted program material as you record, and inserts periods of silence between pieces of music at the press of a button. Finally, at the end of tape, an all-mode auto stop system disengages the heads, pinch roller and capstan. This, together with a special safety-load mechanism, helps preserve tape and transport system from unnecessary friction and wear.
Precise Controls, Convenient Features
In addition, the layout and design of the K35 afford easy, accurate control. Separate, three-position bias and equalization controls optimize the deck for normal, ferrichrome, chromium dioxide (or chrome-equivalent) tapes. Dual-concentric controls provide quick adjustment of record levels and channel balance. Levels are displayed large meters, accurately calibrated from -20 to +5 VU. Musical transients too fast for detection by the meters are clearly indicated on the "peak" LED
